By now we had fully surrendered to the charm of Lugu Lake. We cycled to Caohai Lake, or the Grass Sea, a southern section of Lugu which is known as the soul of the Mosuo people. This part of the shallow lake has a murmuring growth of dense reeds where Mosuo girls dressed in red and white expertly navigate their boats. The color of the water changes throughout the day and there's a huge variety of avian and water life. A 300-meter long wooden bridge connects the two sides of the Grass Sea. Walking Marriage Bridge is the symbolic center of dating culture for the young Mosuo men and women who meet on it to express their affection through dancing and singing. The Mosuo men are referred to by their sweethearts as Azhu and the women by their beaus as Axia. On a clear winter afternoon it was definitely a stirring sight to see a Mosuo youth walking on the bridge across the rippling grass sea. As we stood there, Hong Kong seemed a long way away. Much of China's ancient history has been penned into its ethnically diverse margins. Despite having resisted its fashionable allure for so long, the soul of Lugu had won us over.
